Wrong gas estimates for encrypted ParaTime transfers

まず、--encrypted を使用して secp256k1 アカウントからの暗号化された ParaTime transfer を再現します。最初は --gas-limit なしで実行し、その後、報告された limit を指定して実行します。暗号化された transfer の gas estimation の経路を追跡し、標準的な ParaTime transfer と比較します。推定値で十分であり、limit を手動で増やさずにトランザクションが正常に実行されれば完了です。

Trying to transfer tokens from the secp256k1 account on Sapphire and providing --encrypted incorrectly estimates gas:

1. first attempt (no --gas-limit provided):

Broadcasting transaction...
Error: Transaction check failed with error: module: core code: 12 message: out of gas (limit: 2318 wanted: 11388)

2. second attempt --gas-limit 11388:

Broadcasting transaction...
Error: Transaction check failed with error: module: core code: 12 message: out of gas (limit: 11388 wanted: 11389)

3. third attempt --gas-limit 11389:

Broadcasting transaction...
Error: Transaction check failed with error: module: core code: 12 message: out of gas (limit: 11389 wanted: 11390)

4. fourth attempt --gas-limit 11390:

Broadcasting transaction...
Transaction included in block successfully.
Round:            3995161
Transaction hash: 1dc1246a30e854dede27d48cb1220b4c19d46521ade38622bbda3ea8c2a4e738
                  (Transaction result is encrypted.)
Error: Execution failed with error: module: core code: 12 message: core: out of gas (limit: 11390 wanted: 12389)

^^ the transaction was actually submitted and gas was spent, see: https://explorer.oasis.io/mainnet/sapphire/tx/1dc1246a30e854dede27d48cb1220b4c19d46521ade38622bbda3ea8c2a4e738

5. fifth attempt --gas-limit 12389 finally worked:

Broadcasting transaction...
Transaction included in block successfully.
Round:            3995186
Transaction hash: 7224d59e6b74d9b2caf55ab40dfe0757cef4f71c66d3a7aba3de1d267d2ea409
                  (Transaction result is encrypted.)
Execution successful.

Since gas estimates are standard for transactions such as ParaTime transfers and withdrawals, we could probably just hardcode those?
